Al3Ti was directly utilized as catalyst precursor to examine its catalytic activity in the reversible dehydrogenation of NaAlH4. It was observed that Al3Ti possessed considerable catalytic effect on the de-/hydriding reactions of NaAlH4. The catalytic enhancement by Al3Ti doping significantly increased with increasing ball-milling time. Moreover, it was noted that dehydriding kinetics and cycling performance of the Al3Ti-doped NaAlH4 were highly dependent on the starting material, 1:1 NaH/Al mixture or NaAlH4. The combined property and phase examinations suggest that Al3Ti may act as active species to catalyze the reversible ...
